Specification of Letters Patent.

Patented July 1e, 191s.

Application led April 16, 1918. Serial No. 228,937.

To all 'whom 'it may concern:

Be it known that we, PLEASANT BnAnBUnN and WALTER CHAMBERS, citizens ofthe United States, residing at Muncie, in the county of Delaware andState of Indiana, have invented certain new and useful Improvements inRail-Clamps, of which the following is a specification.

This invention is a rail clamp and has for its principal object theproduction of a. structure which will positively hold the rails fromspreading or slipping from their correct positions when in use.

Anotherobject of this invention is the production of a rail clampwherein a bar is provided and this bar is providedwithrail receivingpockets adjacent its ends, thus perproduction mitting railsto be carriedwithin the pockets, While clamping means is then applied for holding therails against removal from the pockets, thus causing the bar to hold therails against spreading.

Another object of this invention is the with tenons at its ends, thuspermitting clamps to be positioned over the tenons and tixedly securedthereto, whereby the clamp will be held in engagement with the railsmounted upon the bar for holding the rails against accidental movement.i

With these and other` objects in View this invention consists of certainnovel combinations, constructions and arrangement of parts as will behereinafter described and claimed.

One practical embodiment of construction and assembl f the presentinvention, with slight modi cations thereof is hereinafter in thedrawing, in

is provided described, and illustrated whichj Figure 1 is a sideelevation of the rail clamp in use.

Fig. 2 is an enlarged detail perspective view of one end of the har ofthe rail clamp, the clamping block being removed.

Fig. 3 is a slightly modified form of the invention illustrating how thestructure may A be used in connection with a steel tie, thi1s forming anabutment lug upon one side of the rail pocket instead of providing athick--t lened abutment thereadjacent. .j

Referrin to `the accompanying 4drawing' bly numera s, it will he seenthat the rail c amp comprises an elongated bar 1A having thickened endportions `2.

of a rail clamp wherein the bar the Each thickened end 2 is providedwith a transversely extending roove 3, thus forming a rail receiving pocet. The formation of the pocket therefore forms abutment shoulders 4upon each side of the groove, while the thickened end is furtherprovided upon each side of the pocket and communicating with theshoulders 4 with spike receiving openings 5. Adjacent the outer ends 2of the bar 1, are formed the iongitudinally extending tenons 6projecting upwardly from the central portions of the thlckened ends, asshown clearly in Fig. 2. These tenons 6 extend from the outer ends ofthe thickened ends 2 of the bar 1 and terminate adjacent one abutmentshoulder i of the pockets 3 formed in the thickened ends. It Willfurther be noted that the tenons 6 are provided with openings -7projecting therethrough for purposes to be hereinafter set forth.

The clam ing blocks are similarly constructed, and each clamping block 8has an internal pocket 9 formed therein as indicated in dotted lines'"in Fig. 1. The clamping block thus presented is also provided with a.-

rail engaging head 1.0 formed on its for- `ward end, While it isprovided at its rear end 'the t1e and between a pair of adjacent ties.

The rails, as above specified, extend through the pockets 3 in thethickened ends 2 of the har 1 and for this reason the base of the rails-12 will engage the abutment shoulders 4 formed contiguous .to thepockets 3. i The lclamping blocks are then brought into use,

and are positioned over the tenons 6, for at this time the tenons 6 arereceived within pockets 9, formed in the blocks 8,y as illustrated inFig. 1. Bolts erV other securing elementsv 13 are then passed throughthe A blocks 8 and through the olpenings 7 ormed in the tenons6,.thusfirm y connecting the clamping blocks 8 upon the tenons. In this way theblocks will be held to the thickened ends 2 of the bar 1 and as the railengaging heads 10 of these blocks engage the base, the web and also thetread of the rails, itis obvious the railsj will be firmly held in theockets of the bar., Therefore, the bar being adapte of an elongatedconstruction it will positively hold the rails against spreading orspringing from their correct positions. It will be noted that thedepending lugs 11 of the blocks will fit upon the ends of the thickenedends 2 of the bar 1 and will further assist in steadying the clampingblocks and holding the same in their correct positions..

By referring to Fig. 3, a slightlyy modified form of the device isdisclosed wherein the structure is intended to be used in connectionwith a a metal tie 14 which may have an abutment lug 15 struck therefromor formed thereon to enga e the base of the rail 16. The tenon 17 isormed integral with the tie 14. The clamping blocks 18 are positionedover the tenon in the manner similar to which the first form is used andthen suitable securing means is passed through the blocks and thetenonfor securing these elements together to bear upon the rail and holdthe same against displacement in the manner similar to which thepreferred form is used. The principal difference in the modified formand the preferred form resides in the formation of an abutment luginstead of a thickened portion as used upon the bar of the preferredform of the invention.

It is obvious that detail changes may be made in the construction of thepresent invention, without departing from the spirit of the device andfor this reason it is intended to include all such modifications asproperly come within the scope of the invention as claimed.

What is claimed is:

1. In a rail clamp of the class described, the combination of a barhaving rail receiving pockets adjacent its ends, tenons formed u on saidbar and extending to said pockets, c amping blocks having internalpockets formed therein, each block having a rail engaging head at oneend and a depending lug at the o positie end thereof, said heads beingto engage rails fitting within said pockets, while said lugs engage theends of said bar, thus steadying said blocks, and securing means passingthrough said blocks and said tenons for holding said blocks in setposition.

2. In a rail clamp of the class described, the combination of a barhaving receiving pockets adjacent its ends, clamping blocks, each blockhaving a rail engaging head at one end and a depending lug at the oposite end thereof, said heads bein ada ted ib en ga rails fitting withinsaiid poc ets, while sai lugs engage the ends of the bar, thus steadyinsaid blocks. and means for holding said bloc in setr positions upon saidbar.

3.
